unix_chkpwd - Helper binary that verifies the password of the
current user
unix_chkpwd [...]
unix_chkpwd is a helper program for the pam_unix module that
verifies the password of the current user. It also checks
password and account expiration dates in shadow. It is not
intended to be run directly from the command line and logs a
security violation if done so.
It is typically installed setuid root or setgid shadow.
The interface of the helper - command line options, and
input/output data format are internal to the pam_unix module and
it should not be called directly from applications.
